Embodiment Construction

[0042] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0043] refer to figure 1 , the step of searching the target end in the bluetooth connection method of the present invention is as follows:

[0044] Step 100, take the sender as the current node, and pass in the list of parent nodes. At this time, since the sender is the starting node, there is no parent node, so the parent node list at this time is empty.

[0045] Step 101, searching for all nodes connectable to the current node, generating a list of connectable devices, and storing all nodes connectable to the current node into the list of connectable devices.

[0046] Step 102, remove nodes that are duplicated with the parent node list in the connectable device list.

[0047] Step 103, adding the current node to the connection path.

[0048] Step 104, searching how many child nodes...

Abstract

The invention discloses a Bluetooth connecting method, which comprises the steps as follows: using a sending terminal as the current node; searching all nodes which can be connected with the current node to generate a connectable equipment list; adding the current node into a connecting path; searching the number of child node cycles existing in the current node to judge whether all of the child nodes of the current node are target terminals; if yes, establishing a Bluetooth connection, else, using the child nodes of the current node as a new current node; and recursively searching according to the new current node. Users can remotely connect any far Bluetooth equipment in an area which is covered by plenty of Bluetooth equipment, so that the use range of Bluetooth is greatly expanded; therefore, Bluetooth communication is no longer limited in a short distance.

Description

technical field [0001] The invention relates to a Bluetooth connection method, in particular to a Bluetooth long-distance connection method. Background technique [0002] Today's mobile phones are becoming more and more powerful, and Bluetooth has become a standard configuration. The communication method between mobile phones is no longer limited to GSM / GPRS, and Bluetooth also plays an important role in the wireless communication method of mobile phones. Bluetooth has the advantages of simple communication, fast transmission speed, and no network requirements. But at the same time, Bluetooth also has the disadvantage of short transmission distance. [0003] Take the establishment of a simple Bluetooth connection between mobile phones as an example. At present, the Bluetooth transmission distance is generally only within 10M, but in reality, due to various interferences, the distance will be shorter. But it is impossible to realize direct long-distance Bluetooth device co...
